Morespecifically 10 indicates the casing of a door-lock which isfittedwith a latch 11, a bolt 12, a transverse shaft 13,for operatingthe latch, and ihnerand outer knobs 14; and 15 respectively for turningthe shaft,

the outer knob being normally in such relation to the shaft and catchthat it may be turned; without actuating the catch or bolt. The outerknobis hollow and is fitted with a keyless 'lock 16 by which this knobor the shaft may be placed in operative relation to the latch.

In thefform of the invention shown. in Figures 1 and 2, the knobs areengaged with the shaft and the latter is moveable longitudinally inrespect to the knobs to throw it in and out of operative relation toeither the latch or bolt and the outer knob is connected to the shaft atall times, whileinthe modified. form shown in Fig. 3, the inner knob isfixed on the shaft which is always in operative relation to the catch,and the outer knob is adapted to be thrown in and out of engagement withthe shaft.

The outer knob 15 is fitted with a hub 17 which bears in a collar18 onthe lock casing and is formed with a peripherial channel 19 engaged by apin or screw 20 on the collar to hold the knob 15 against longitudinalmovement, yet permit -;its being rotated. The innerknob is provided witha hub 21, which, iwhen the shaft is reciprocal, bears in a collar 22 onthe lock casing and is formed with a peripheral channel 24 engaged by ascrew 25 onthe collar to hold the knob 14c againstlongitudinal movementyet with the arm, the shaft niayfbe rotated to dispose the finger'infront of thearm to retract thelatch in opposition to. asprin'g32 the armbearing against a shoulder 33 on the latch during this operation, but onretating the shaft in an opposite direction the finger will rock the armand pass freely therebeneath without operating the latch, which isnormally maintained in its forward position by the spring 32. When it isdesired to actuate the bolt the shaft 13 is moved longitudinally toalign the finger 28 and studs 29-80 whereupon on rotation of the shaftthe finger may engage stud 29 to advance the bolt or engage stud 30 toretract the bolt.

Any suitable means may be employed for effecting engagement betweentheshaft 13 and knobs 14 and 15 whereby the shaft may "be movedlongitudinally in the knobs and yet remain in rotative engagementtherewith, but which is here shown as accomplished by forming the shaftsquare and providing thehubs'of the knobs with square openings toreceive the shaft.

Theshaft isnormally disposed inits latch operating position by means ofa spring 34 which bears between the hub 17 and a flange 35 on the shaft.

As a means for enabling a person ,to effect longitudinal movement of.the shaft from the inside 'of the door, the inner end of the shaft isfitted with a head 36' projecting through thejknob, which has a shoulder37 to abut against the knob to limit outward movement of the shaft underaction of the spring 34. i

In the form of the invention shown in Fig. 3, a .collar3 8 is fixed onthe shaft 13 and has a finger'39 arranged in operative relation to astud 40 on the'latch ll the shaft being held against longitudinalmovement by a' pin 41 on the casing 10 extending into a periph'eralchannel 42' on the shaft. The outer end of the shaft is formed with achannel .43 to receive a tongue 44 on a slide-bar 45 mounted in the hubfor longitudinal reciprocal movement and held against rotation relativeto the knob. A spring 46 is arranged to act .on the bar and normallyhold the tongue out of engagement with the slot. The lock bolt 12 shownin the drawing in Figure 3 may be operated by a key in' the mannercommon to door looks, or may be eliminated, as the operation of the bolt12 is not affected by the lock mechanism controlling the latch bolt 11.

It will now be seen in the arrangement shown in Fig. 1, that when theshaft 13 is in its normal advanced position the latch may be operated byturningeither the inner or outer knobsand that the bolt 12 cannot beoperated without first retracting the shaft 13 to position the finger 28in'alignm'ent llih S S 29-3 61 1 1. ol and tha y ang ment sho n n F g-.3, the

cann t be pej eclby the oute k b ith Means are provided controlled bythe keyless lock, whereby retraction of the members 13 or 45 may bemanually effected from the outside of the door to unlock the latter byturning the knob 15, which means embodies a disk 47 mounted in the knobto have combined rotary and longitudinal movement relative thereto.

The mounting of the disk embodies a pair of oppositely inclined flanges4849 projecting inwardly from opposite sides of the knob on the outersides of which the inner face of the disk seats.

The circumferential periphery of the disk bears on an annular wallformed on the knob, a flange 50 on the disk being adapted to vabutagainst a shoulder 51 on the knob to limit inward movement of the disk.To advance or retract thedisk in relation to the knob, screw engagementis effected between the disk and knob by means of a bolt 52 extendingtransversely through a projection" in Figs. 1 and 3; the ends of flangesbeing spaced apart to permit the bolt being passed from the. outer tothe inner sides thereof. It will now be seen that on turning the disk inone direction the bolt in riding on the inclined flanges will act toadvance the disk inwardly so that the projection 58 on the' disk whichbears {against the outer ends of the shaft 13 or bar 45 will act toadvance theshaft .or bar in opposition to the springs "34 or 46.

Means are provided for effecting a locking, engagement between the bolt.and the knob to fasten the disk against rotation either in itsadvancedor retracted position, and embodies serrations 54 and 55 formed on theknob adjacent the undersides of the flanges 48 and 49; the projections56 of the serrations 54 being arranged dimetrically opposite thedepressions 57 of the serrations 55 so that when one end of the boltrides over a projection 56 the bolt will be moved lengthwise so that itsother end will extend "into a depression. 57. By locking the bolt inthis position the disk will be held against turning. For this purpose Ipreferably employ a push-pin controlled locking mechathe slots 72 in thecasing.

- combination.

reopen groove 62 and hasa series of circumferential channels 63, andmounted on-each tumbler is a spring pressed pin 64 which rides in achannel 63 and is adapted to be positioned in alignment with the grooveto permit longitudinal movement of the bolt under action of a spring 65.When all the tumblers are arranged with the pin 64 in alignment with thegroove the bolt is free to move in either direction, but when one of thepins is out of alignment with the groove the bolt will be locked. i i yI A certainnumber of impulses must be imparted to each tumbler from astarting position to dispose thepins in the groove aligned position. Todetermine the starting position, a spring pressed indicator pin 66 isarranged in the disk and positioned to be actuated by each ratchet toothas the tumbler is rotated. A filler 67 is provided to eX- tend into arecess between adjacent ratchet teeth to effect a lesser movement of thepin so that the position of the fillermay be readily ascertained, whichfiller is so disposed as to indicate the starting position.

As a means for reminding a person of the combination of impulses thatare to be given the several push-pins to unlock the bolt 52, I providethe device shown in Fig. 9, which comprises a casing 68 containing aseries of pins 69 mounted to rotate and held against longitudinalmovement, which pins have screw threaded portions engaging sleeves 70formed with points 71 extending through Numbered graduations 7 3 arearranged at the sides of the slots which are indicated by the pointer.When the combination of the lock is ascertained the pins 69 are turnedto dispose the pointers adjacent the graduation bearing the numbercorresponding to the number of the This device can be carried on theperson or placed in a convenient place, so that if the combination ofimpulses is forgotten, it is readily determined by glancing at thenumbers indicated by the pointers in the slots.

The operation of the invention is apparent from the foregoing, it beingseen that on turning the disk to move it inwardly the outer knob will bethrown into operative relation to the doorlock in which it may bemaintained by locking the disk in its innermost position so that onturning the knob '15 the door may be unlocked. When the disk is in itsoutermost position the outer knob will be out of operative relation tothe door lock and accordingly the lock cannot be unlocked from theoutside of the door.
